Algebra.Com's Answer #432847 by jim_thompson5910(35256) ![]() You can put this solution on YOUR website! All 3 angles must add to 180, so\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "S+M+L = 180\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Plug in L = 3S to get\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "S+M+3S = 180\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4S+M = 180\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Then plug in S = M-30 to get\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4(M-30)+M = 180\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4M-120+M = 180\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Solve this for M. Once you have M, you can find S using S = M-30. Once you have S, you can find L using L = 3S. \n" ); document.write( " |
